> Your keybinding to go to the next quickfix item doesn't work in a location list because it uses :cn^M, but the location list wants :ln^M or whatever.

Navigating quickfix and location lists is global, so a single common command wouldn't make sense (you can use `:cn` from any window -- even if the quickfix is not visible). However, you could use a `<buffer>` map to use the same key to navigate within loclist/quickfire windows.

Their entire concept is to be what quickfix isn't: instead of a global list, it's a list that's tied to a window. I can't think of features that a loclists have but quickfix doesn't unrelated to their nonglobal nature.

I can't claim vim's code is easy to understand, but this is not a fair complaint.
